testing leaking/burnt valve
Will a leakdown or compression tester tell me if i have a non seating valve?
I get the general idea how one works, how do you tell if its a valve thats not sealing?

every since then the car shakes/ misses at idle , and has some valvetrain noise
I figure ill check the vacuum , and then do a leakdown test

i switched from crane 3/8 sa to promag 7/16 nsa, plugs were all pulled i ran it with 1/8 turn past and also tryed 1/4 no difference
i went thru every sensor on the car, motor mounts, plugs,wires etc, so i think a leakdown test will help tell me whats going on
